Resize Image to 30KB
Some board exam and registration forms set their limit between the very tight 20KB signature cap and the more common 50KB photo cap — 30KB is that in-between number, common enough on specific registration portals to be worth its own preset rather than only reaching it through a custom target. Reduce image size now.
How it works:
- Upload your photo or scanned document.
- 30KB is pre-selected.
- Adjust quality slightly if the form also specifies a minimum dimension — reducing quality first before touching dimensions usually preserves more detail at this size.
- Download.
Why 30KB specifically:
it sits close enough to 20KB that a signature or simple graphic compresses cleanly, but it gives a small photo a bit more room than 20KB would — useful for forms that ask for a compact photo rather than only a signature. If your requirement is phrased as reduce image size less than 30KB, the same 30KB preset already covers it, since it targets at-or-under.
Frequently Asked Questions
Is 30KB different from 20KB or 50KB in how the tool works?
No, same tool, same process, just a different starting target. Try 30KB first if your form specifies that number exactly; use 20KB or 50KB if it doesn’t.
